AP Automation, short for accounts payable automation, is software that automates invoice receipt, approval, and payment. It eliminates the need to enter invoice data manually, chase approvals through email, or track everything in spreadsheets. Using AI, AP Automation captures invoice details, validates them, routes approvals, and syncs everything with your ERP. Here's how it works. Invoices come in through email, PDFs, scans, or other electronic formats. The system pulls out the data, matches it to purchase orders or receipts when needed, flags anything that looks off, and moves invoices through the approval process. The result is faster processing, fewer errors or duplicate payments, stronger controls, and real time visibility into what's pending, approved, or due, which is critical for teams managing growing invoice volumes, tighter compliance requirements, and faster close cycles. Put simply, AP Automation helps finance teams handle invoices faster, more accurately, and with better control.
